Answer 1

Ответ:

Пошаговое объяснение:

-0,5(8х + 9) - 6,9 > 4х

-4х - 4,5 - 6,9 > 4х

-4х - 11,4 > 4х

-4х - 4х > 11,4

-8х > 11,4

х < 11,4 : (-8)

х < -1,425

х € {-∞, -1,425}

Answer 2

To solve the inequality -0.5(8x + 9) - 6.9 > 4x, we can follow these steps:

1. Distribute the -0.5 to the terms inside the parentheses: -4x - 4.5 - 6.9 > 4x

2. Combine like terms: -4x - 11.4 > 4x

3. Add 4x to both sides of the inequality to isolate the variable: -4x + 4x - 11.4 > 4x + 4x -11.4 > 8x

4. Divide both sides of the inequality by 8 to solve for x: -11.4/8 > 8x/8 -1.425 > x

So, the solution to the inequality -0.5(8x + 9) - 6.9 > 4x is x < -1.425.

Please note that this solution is based on the given inequality and the steps used to solve it. If you have any further questions or need clarification, feel free to ask!
